Based on the sum and the share value after the relevant number of years, Charlotte's share is $4,137.46 and Ali's share is $3,752.54.

This can be solved using the substitution method:

Alice share + Charlotte's share = 7,890

As + Cs = 7,890

As = Cs

(As x Future value factor, 5%, 8 years) = (Cs x Future value factor, 5%, 6 years)

(As x 1.47745) = (Cs x 1.3400)

Cs = (As x 1.47745) / 1.3400

Cs = As x 1.1025746

Slotting these back in the original formula gives:

As + (As x 1.1025746) = 7,890

2.1025746As = 7,890

,As = 7,890 / 2.1025746

= $3,752.54

Charlotte's share will be:

= 7,890 - 3,752.54

= $4,137.46

The solution (3, -2).

Step-by-step explanation:

The easiest way to find this solution is inputting these two equations into Desmos Graphing Calculator!

Answer:

x = 3,y = -2

Step-by-step explanation:

Given data:

Y= -2

4x -3y=18

Solve:

Substitute the given y-value into 4x−3y=18 and solve for x

Since, y = -2,

[tex]4x-3(-2)=18[/tex]

[tex]4x+6=18[/tex]

[tex]4x+6-6=18-6[/tex]

[tex]4x=12[/tex]

Answer:

~Y/n here~ I would think that the greater the slope the steeper the line. b is the slope of the line. So the slope means that a unit change in x, so the independent variable will result a change in y by the amount of b. Slope can show both steepness and direction in a linear function.

Answer:

Recursive formula of an arithmetic sequence is given by the expression,

                          Tn=a+(n−1)d

                 Where, Tn= nth term

                              a= First term of the sequence

                              n= Number of term

                              d= Common difference

Therefore, number of sticks in the 6th pattern are 32.

                   And number of sticks in the nth pattern are Tn=5n+2

From the picture attached,

Number of sticks in 1st pattern = 7

Number of sticks in 2nd pattern = 12

Number of sticks in 3rd pattern = 17

Sequence formed is 7, 12, 17..... nth term

This sequence has a common difference of 5 in each successive term so it will be an arithmetic sequence.

Therefore, nth term of the sequence will be,

       Tn=a+(n−1)d

       Tn=7+(n−1)5

       Tn=5n+2

If n=6,

       Tn=7+(6−1)5

       Tn=7+25

Tn=32

Hope it helps !

Answer:

7.50 (nearest hundredth)

Step-by-step explanation:

General form of geometric progression:  [tex]a_n=ar^{n-1}[/tex]

(where [tex]a[/tex] is the initial term and [tex]r[/tex] is the common ratio)

Given progression:

[tex]5\left(\dfrac13\right)^{n-1}[/tex]

Therefore:

Sum of a geometric series:

[tex]S_n=\dfrac{a(1-r^n)}{(1-r)}[/tex]

Substituting a = 5, r = 1/3 and n = 10 to find the sum to n = 10:

[tex]\implies S_{10}=\dfrac{5(1-\frac13^{10})}{(1-\frac13)}[/tex]

[tex]\implies S_{10}=7.499873987...[/tex]

Answer:

Solution,

0.02×100=2

I think it will help you.

The product 0.02 x 100 = 0.02 x 10² =2

A number system is defined as a system of writing to express numbers.

The given is 0.02 x 100

We need to find the product of zero point zero two times of hundred.

This we can do by using the operation multiplication.

Multiplication is a method of finding the product of two or more numbers

We know that 100 we can write in the form of 10²

When 0.02 is multiplied with 10² we get 2

Hence, the product 0.02 x 100 = 0.02 x 10² =2

Answer: 9 houses

Step-by-step explanation:

Step 1:

Since 2/3 of the houses were sold last month, 1/3 of them were left.

45 * 1/3 = 15 houses left last month

Step 2:

Since 2/5 of the remaining houses were sold this month, 3/5 of them were left

15 * 3/5 = 9 houses left to be sold

Answer:

37 over 4

Step-by-step explanation:

Hi! I hope you're enjoying your day!

First, 9 times 1 is 9 (anything times 1 is itself)

Now, 9 over 4 is 9 divided by 4.

Is 9 divided by 4? Nope!

However, don't worry! The answer will be a fraction.

[tex]\bold{\displaystyle\frac{9}{4}}[/tex]

Can this fraction be reduced? No.

Why? Because 9 and 4 have no common factors, except 1.

And if you divide by 1, nothing will change.

Hence, the answer is

Improper Fraction: [tex]\boxed{\boxed{\bold{\displaystyle\frac{9}{4} }}}[/tex]

Mixed Number: [tex]\boxed{\boxed{\bold{2\frac{1}{4} }}}[/tex]

Hope everything is clear.

Step-by-step explanation:

Since the ball is going upwards, then down, we have a parabola.

In the form of

[tex] - {x}^{2} + bx + c = 0[/tex]

The leading coeffeicent is negative because we are increasing then decreasing.

Let use t for seconds and h is height.

So we have a function

[tex]h(t) = - {t}^{2} + b(t) + c[/tex]

Since I'm have no information: I'm use calculus and physics to solve this.

All objects fall at the speed of

[tex] - 9.8 \frac{m}{ {s}^{2} } [/tex]

Which is the unit for acclereation.

Since we have are trying to a poisition versus time function, note that the anti derivative of acclereation will give us velocity. So let calculate that

[tex] \frac{d}{dx} (a) = - 9.8x[/tex]

Then note that the anti derivative of velocity is poistion.

[tex] \frac{d}{dx} (v) = - 4.9 {x}^{2} [/tex]

So we know our leading coeffeicent, is -4.9x^2.

The ball is initially launched at a speed of 15 m/s. So the first derivative of the function at x=0, should be 15.

[tex] \frac{d}{dx} (x) = - 4.9 {x}^{2} + bx[/tex]

[tex]v = - 9.8x + b[/tex]

Since 0 times anything is 0, b must be 15 in order to have a first derivative of 15.

Since 0,1 is the y intercept, c will be 1.

So our answer is

[tex] - 4.9 {x}^{2} + 15x + 1 = 0[/tex]

b). When x=1, we get a height of 11.1. Plug in 1 into the function, and we get 11.1

c). Set the function equal to zero and use quadratic formula to solve. You will get 3.13 seconds.

d. The max occurs when the velocity is 0. So we can first differentiate the function, which we will get

[tex] - 9.8x + 15 = 0[/tex]

Then we solve for x.

We get 1.5 seconds. Then plug in 1.5 into the function, we get 12.5. So the max height is 12.5 and this occurs at 1.5 seconds.

e).
